What to do
- Check whether you’re in it.Search your email address on Have I Been Pwned. It tells you which breaches it appears in, Upstox among them, without showing the data.
- Change your Upstox password.If the account still exists, sign in at Upstox (upstox.com) and change it.
- Change it anywhere you used the same one.Start with your email, then banking and shopping. Leaked passwords are tried on other sites automatically, within days.
- Use a password manager and two-step sign-in.A different password for every site means one breach can’t open the rest. Two-step sign-in stops a leaked password working on its own.
- Distrust messages that mention Upstox.Scammers use breach data to sound genuine. Don’t click links in emails or texts about the breach; go to the site yourself.
- Put a PIN on your phone account.Ask your mobile provider for a port-out PIN, so no one can move your number to their SIM.
- Freeze your credit.In the US, free at Equifax, Experian and TransUnion. In Australia, ask Equifax, Experian and illion for a ban. No one can open credit in your name while it’s on.
- Watch your statements.Report anything you don’t recognise to your bank, and ask for a new card if full card numbers leaked.
